I need advice from computer gurus

[jagash]

More precisely, i need shops. I purchased my motherboard with an oversized fan about a year and a half ago. He said it was "a little bigger then spec, but hasn't had any problem". Managed to ID the problem, being that the weight slowly broke the thermal paste connection between the cpu and it's fan. This naturally caused stupid heating problems and means that my computer is on it's side as a temporary fix. The plan is to get thermal pads and a new cpu cooling system of some variety.

Unfortunately we have been depending on Deals Direct for about a decade for all new hardware so we are at a loss of where to get the goods. Firstly, where should we go for said hardware? Secondly, what cooling system would you recommend?

Cheers
